ADHESION-MODIFIED EXPANDABLE POLYOLEFIN COMPOSITIONS AND INSULATED VEHICLE PARTS CONTAINING EXPANDED ADHESION-MODIFIED POLYOLEFIN COMPOSITIONS

摘要

Polyolefin compositions that expand freely to form stable foams are disclosed. The compositions contain specified levels of adhesion-promoting resins. The compositions include at least one heat-activated expanding agent and typically include at least one heat-expanded crosslinker. The compositions are effective as sealers and noise/vibration insulation in automotive applications.
